The last ice age ended about 11,700 years ago, with the Last Glacial Maximum around 26,000–20,000 years ago. The cited chronology does not establish two complete glacial-interglacial cycles within 36,000 years, and glacial and interglacial stages themselves last thousands to tens of thousands of years. The video argues that the rise and fall of civilization resembles the sawtooth pattern of biological life and that some societal collapses coincide with geological or cosmic events. That pattern is the video's interpretation, not an established correlation, and the glacial evidence does not substantiate ecological changes occurring within single-digit years.
Video proposes a sawtooth cycle linking civilizations, extinctions and climate
Key facts
- The last ice age ended about 11,700 years ago, while the Last Glacial Maximum occurred roughly 26,000–20,000 years ago.
- The cited chronology does not establish two complete glacial-interglacial cycles within 36,000 years; glacial and interglacial stages last thousands to tens of thousands of years.
- The video argues that civilizational rise and fall resembles the sawtooth pattern of biological life and that some societal collapses coincide with geological or cosmic events.
- The glacial evidence does not establish a civilization-extinction correlation or substantiate ecological changes within single-digit years.
